------***------Abstract - This paper mainly emphasizes on the Persistence space at such a high frequency that a two dimensional Of Vision technology. In current era in which energy is the display is visible. main factor in designing all the applications, maximum and efficient use of the energy is very important. A POV display has 2. WHAT IS PERSISTENCE OF VISION many advantages over a traditional CRT, LCD or LED display, like power savings, less complexity, easy configuration, Persistence of vision refers to the optical illusion whereby attractiveness etc. To overcome the drawback of old processor multiple discrete images blend into a single image in the we have decided to implement the same display atop a new human mind. Our eyes offer one of the five specialized means and advanced microprocessor, the Arduino nano. This by which our mind is able to form a picture of the world. The platform brings with it newer coding and a different eye is a remarkable instrument, having certain characteristics understanding of peripherals. ARDUINO INTERFACE BOARDS to help us process the light we see in such a way that our provide us with a low-cost, easy-to use technology to create mind can create meaning from it. Take the motion picture, the project. We also aim to build the newer display to work the scanning of an image for television, and the sequential with modern forms of interfaces. To accomplish this, we will be reproduction of the flickering visual images they produce. interfacing the display with an Android device. This project These work in part because of an optical phenomenon that can be implemented with help of any Android has been called persistence of vision and its psychological Smartphone/tablet running Android 4.0+. partner, the phi phenomenon; the mental bridge that the mind forms to conceptually complete the gaps between the Key Words: POV, Arduino nano, Android, ATMega 328, USB frames or pictures. Interfacing, Piranha LED 3. SYSTEM DESIGN 1. INTRODUCTION The core phenomenon on which the entire project is based is the Persistence of vision. Persistence of vision is the phenomenon pertaining to the human eye by which an after image is thought to persist for approximately one twenty- fifth of a second on the retina. The way this phenomenon of persistence of vision works is based on the belief that human Fig - 1: Proposed Block diagram perception of motion (brain centered) is the result of persistence of vision (eye centered). Any motion that we see Persistence of vision is an optical illusion in which many around us is the direct implication of persistence of vision discrete images are blend into one single image on the phenomenon at work. Persistence of vision is still the human mind. This particular board has a set of 8 inline LEDs accepted term for this phenomenon in the realm of cinema that you can program to display the POV effect. We have history and theory. Blinky POV is a reprogrammable LED kit already implemented a POV display based on Arduino Nano. that uses persistence of vision to create the illusion of text or The display used is based on Arduino Nano that is used to a small picture floating in the air. The purpose of this project control the switching of 8 red colored LED’s is to design and create a persistence of vision (POV) display. The display will allow the users to upload an image to be The display consisted of the following components displayed through the wireless communication. A persistence of vision (POV) refers to the phenomenon of the 1. Arduino Nano: Processor used is ATmega328. Arduino human eye in which an after image exists for a brief time Nano consists of 14 Digital input output pins and 8 Analog (10ms). A POV display exploits this phenomena by spinning input pins. It is used for switching theLED’s at appropriate in one dimensional row of LED’s through a two dimensional time.

2. Gear Motor: Used to rotate the assembly at high speed to induce the persistence of vision effect. We are using a DC Motor of 300rpm.

3. LED display: 8 general purpose LEDs strip Used as display agents.

4. Battery: We are using 3.7V (LiPo) battery.

First we have to give a power supply of 12v 1Amp is given to 6. CONCLUSIONS the Gear Motor which is 300rpm and another supply from the Battery which is 3.7v LiPo Battery given to the Arduino Nano, The conventional LED displays used in advertisements and LEDs, Opto Sensor. Whenever we turn ON both Power supply information display uses an individual matrix of LEDs for then motor starts rotating with his actual speed. Here we each character. For example in a display using 8X4 Led connect a small obstacle for that obstacle the IR rays of Opto matrix for a single character, 10X8X4 LEDs would be sensor will be breaks this breaking of IR rays transistor will required to display a word consisting of 10 characters, be trigger and because of this transistor LEDs start to increasing the circuit complexity. Our circuit uses a low blinking after every 2milliseconds. When the motor are power Arduino nano board, with 7 multi-color LEDs and a rotating LEDs are also rotating and generate actual name acts like display this vision is called as Persistence of Vision low power motor. This technology saves power monumentally. The display is configurable to show any 5. SYSTEM MODEL pattern in any color through an Android device that dictates its output as shown in figure 3. The display is extremely attractive to look at and gives a sense of being a transparent display. By using a motor of higher RPM, one can achieve more clarity in the display.
